RE-MX2000-1800x4 CB-RE Boot Sequence

The router is shipped with the Junos OS preinstalled on the CB-RE. There are three copies
of software:
One copy on the CompactFlash card in the Routing Engine.
One copy on a USB flash drive that can be inserted into the slot on the CB-RE faceplate.
The Routing Engine interface boots from the storage media in this order: the USB device
(if present), then the CompactFlash card, then the LAN. Normally, the router boots from
the copy of the software on the CompactFlash card.
